Feature Request — Comment Reactions API

Feature Request

Hi Zernio team!

I'm using your platform with an n8n workflow that auto-replies to
Facebook page comments. Everything works great, but I'd love to
suggest a new feature.

🎯 Feature Request — Comment Reactions API

Currently your API supports comment REPLY:
POST /api/v1/inbox/comments/reply

But there's no way to add a reaction (Like, Love, Haha, etc.)
to a comment. This is one of the most common engagement actions
on Facebook pages.

📋 Suggested API endpoint:
POST /api/v1/inbox/comments/{commentId}/reactions
Body: {
"accountId": "xxx",
"reactionType": "LIKE" | "LOVE" | "HAHA" | "WOW" | "SAD" | "ANGRY"
}
Or to remove:
"reactionType": null

Underlying Facebook Graph API endpoint already supports this:
POST /{comment-id}/reactions
(Permission: pages_manage_engagement)

Your accounts already have this permission scope (I can see
"pages_manage_engagement" in /api/v1/accounts response).

💼 Business value:
Auto-engagement boosts FB algorithm visibility
Customer feels acknowledged when page reacts to their comment
Common UX pattern that Sprout Social, Hootsuite already support
Many small businesses (like mine — Suvd Salon, Mongolia)
would adopt this immediately

🌍 Use case (mine):
- I run a Mongolian beauty salon Facebook page
- Customer comments on a post like "What's the price for jacuzzi?"
- My n8n bot auto-replies with the price
- I'd love to also auto-❤️ the comment to show appreciation

Would love to see this added to your roadmap! Let me know if
there's a public roadmap I can vote on, or if there's a
specific channel for feature requests.

Thanks for the great product!

Best,
Tsedendorj

    This works today, just under a different name: POST /v1/inbox/comments/{postId}/{commentId}/like with { "accountId": "..." } likes a Facebook comment as the Page, and DELETE on the same path removes it. It runs on pages_manage_engagement, which your accounts already hold, so the n8n auto-engagement flow you describe works right now.

    Reaction types beyond Like are not possible on Facebook: Meta's /reactions edge is read-only and POST /{comment-id}/likes is the only reaction a Page can publish, so LOVE, HAHA and the rest cannot be sent by us or by any other tool. LinkedIn is the one platform with a richer set, and there the same endpoint accepts reactionType (PRAISE, EMPATHY, INTEREST, APPRECIATION, ENTERTAINMENT).
